Hey All,


I have a question and I was wondering if anyone has stumbled onto this.


I bought a MBP about three weeks ago and suddenly ran into this issue.


Whenever I open VLC to play a movie, the colors on the monitor seem to wash out and look like the contrast of the display has been turned way down. As soon as I close VLC the colors seem to return to normal.


I thought that this might be tied to the feature in the settings where the computer can automatically adjust the screen brightness but I disabled that and the problem still persists.


I tried to take a screenshot to show this but when I take a screenshots the two come out the same. What on earth is this????

    Don't panic!  Apparently, it's a graphics card switching issue that appeared in OS X 10.7, was fixed in 10.7.3 and has reappeared in 10.8.  Interestingly, I had the same problem when I bought my MBP at the end of July, but appears to have gone away after updating to 10.8.1 although, this wasn't a listed bug fix.


    This is a problem that has been logged with Apple as the guys on the local Genius Bar have experienced it with their own MBPs and have reported it.


    A "fix" listed elsewhere on this forum is to switch off automatic graphics switching (in System Preferences > Energy Saving) and reboot your MBP.  The colours should come true after the reboot and, because the graphics switching is turned off, using graphically intensive software does not switch to the nVidia card (because it's already switched on) so does not trigger the colour changes you have experienced.


    I, along with many others await an official fix from Aplle, but until then, I hope the above helps with your problem.
